New radiator

[Dave 57]

I have just replaced an old single rad with a double. Whilst installing it I fitted a trv to the return side of the rad which is a Regis valve from B&Q. I have refilled the boiler(combi) and bled all the other rads. Now when the heating comes on in the morning I can hear the new rad gurgling for about two or three minutes. Can anybody tell me what the issue may be.
Thanks in advance Dave[/url]

Hi Dave, try putting the trv on the flow side as the gurgling noise is the water passing through the radiator against the trv as it is trying to operate. Then vent all the radiators.

Thanks for the reply I'll give it a go. The valve does have two stamped arrows on it indicating a two way set up but reading back through previous threads people still seem to prefer using the feed side.
Thanks again
Dave
